Abstract

Reports on a survey of teenagers at a school in Edinburgh, Scotland, conducted as part of the Household Information System (HIS) project at Queen Margaret College. HIS has attempted to apply organizational models of information management to non organizational contexts such as households. Information management concepts have also been complemented by reference to research from sociology and media and cultural studies into the domestic consumption of technologies. Previous HIS research has suggested that notions of technological convergence proposed by producers and suppliers of Information and Communication Technologies (ICTs) are not shared by consumers who prefer to keep their television and computing devioces separate. Television is most often associated with relaxation and entertainment, computing with work and education. However, there is some evidence that expertise with regard to new ICTs is the province of children rather than adults in many homes, a trend which may indicate as inversion of traditional patterns of knowledge dispersal in adult child relationships

Abstract

The Household Information Systems (HIS) project in Queen Margaret College was funded to explore the use of new media in a group of Edinburgh households (Davenport & Higgins, 1995). One of the motivations of the HIS 'programme' was to find a suitable theoretical and/or exploratory framework, which takes account of multiple aspects of behaviour surrounding technologies, and thus avoids assumptions about their role in information-seeking or other isolated activities. A focus on single activities would occlude knowledge of other motivations: bonding, killing time, defining boundaries. In Phase One, `information management' rather than `information seeking' was used as a conceptual framework, embracing work on the `life cycle' of ICTs as illustrated by Kopytoffs `biography of things' approach (1986), Johnson's cultural circuit (1986), research on households as micro-organisations by McCrone and his colleagues (1994), and work by Silverstone and others on ICTs in the home as tools for internal and external adaptation (Silverstone, 1994, Silverstone et al 1994). The `management' framework has been productive - Phase One allowed us to identify patterns of ICT acquisition and deployment in the home, and, more interestingly, structures of appropriation which reflect rules, roles and responsibilities in individual households. These constitute what may be called a `reproduction lattice' (adapting terminology used by Kling (1987) in his analysis of the `web of computing' in organisations), a structure which captures the political and cultural economy of a household. Phase One's findings are consistent with those of other researchers working in the area of domestic consumption of ICTs but a major limitation of the work is the homogeneous nature of the respondents. Among our Edinburgh 'household managers', internal culture was a more compelling explanation for use than technical functionality.

Abstract

Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

Abstract

n this article, we report on the first large-scale study of end-user understanding of subject headings. Our objectives were to determine the extent to which children and adults understood subdivided subject headings and to suggest improvements for improving understanding of subject headings. The 1991 Library of Congress Subject Subdivisions Conference suggested standardizing the order of subject subdivisions for the purpose of simplifying subject cataloging, which served as the impetus for the study. We demonstrated that adults understood subject headings better than children; however, both adults and children assigned correct meanings to less than half of the subject headings they examined. Neither subject heading context nor subdivision order had an effect on understanding. Based on our findings, we challenge the library community to make major changes to the Library of Congress Subject Headings system that have the potential to increase end-user understanding of subject headings.

Abstract

Describes the technique used to study hypertext systems from a very general point of view, focus on monitoring searchers' behaviour, predict the estimation of the ultimate goals of the searchers, and estimate the searchers' determination to find these goals. The components are combined via a Markov chain approach so as to study information retrieval in general and hypertext (hypermedia) in particular. Demonstrates how these estimations can be used to assist searchers during their searching process and presents the derivation of a relevance function for documents, based on these estimations

Abstract

Over the last 4 years, the Information Interaction Laboratory at Rutgers' School of communication, Information and Library Studies has performed a series of investigations concerned with various aspects of people's interactions with advanced information retrieval (IR) systems. We have benn especially concerned with understanding not just what people do, and why, and with what effect, but also with what they would like to do, and how they attempt to accomplish it, and with what difficulties. These investigations have led to some quite interesting conclusions about the nature and structure of people's interactions with information, about support for cooperative human-computer interaction in query reformulation, and about the value of visualization of search results for supporting various forms of interaction with information. In this discussion, I give an overview of the research program and its projects, present representative results from the projects, and discuss some implications of these results for support of subject searching in information retrieval systems

Abstract

In information needs, seeking and use (INSU) research, individuals have most commonly been perceived as users (e.g., Kuhlthau, 1991; Dervin & Nilan, 1986; Dervin, 1989; Belkin, 1980). The concept user originates from the user of libraries and other information services and information systems. Over the years the scope of the concept has become wider and it is nowadays often understood in the sense of seekers of information (e.g., Wilson, 1981; Marchionini, 1995) and users of information (e.g., Streatfield, 1983). Nevertheless, the concept has remained ambiguous by being on the one hand universal and on the other hand extremely specific. The purpose of this paper is to map and evaluate views on people whose information behaviour has been in one way or another the core of our research area. The goal is to shed some light on various relationships between the different aspects of doers in INSU studies. The paper is inspired by Dervin's (1997) analysis of context where she identified among other themes the nature of subject by contrasting a `transcendental individual' with a `decentered subject', and Talja's (1997) presentation about constituting `information' and `user' from the discourse analytic viewpoint as opposed to the cognitive viewpoint. Instead of the metatheoretical approach applied by Dervin and Talja, a more concrete approach is valid in the present analysis where no direct arguments for or against the underlying metatheories are itemised. The focus is on doers in INSU studies leaving other, even closely-related concepts (i.e., information, information seeking, knowledge etc.), outside the scope of the paper.

Abstract

Previous empirical studies of searcher behaviour have drawn attention to a wide variety of factors that affect performance; for instance, the display of retrieved results can alter search strategies (Allen 1991, 1994), the information need type influences search behaviour, (Elkerton et al 1984, Marchionini 1995); while the task complexity, reflected in the information need can affect user's search behaviour (Large et al 1994). Furthermore, information source selection (Bassilli 1977), and the user's model of the system and domain impact on the search process (Michel 1994); while motivation (Solomon 1993, Jacobsen et al 1992) and the importance of the information need (Wendt 1969) also influence search duration and the effort a user will employ. Rouse and Rouse (1984) in a review of empirical studies, summarise a wide variety of variables that can effect searching behaviour, including payoff, costs of searching, resource available, amount of information sought, characteristics of the data and conflicts between documents. It appears that user behaviour is inconsistent in the search strategies adopted even for the same search need and system (Davidson 1977, Iivonen 1995). Theories of searcher behaviour have been proposed that provide explanations of aspects of end-user behaviour, such as the evolution of the user's information need and the problems of articulating a query, [Bates (1979, 1989), Markey and Atherton 1978], effective search strategies in browsing and goal directed searches [Marchionini 1995, Belkin (1987, 1993)], the linguistic problem of matching search terms with indexing terms or content of target documents through an expert intermediary (Ingwersen 1982) or cognitive aspects of IR (Kulthau 1984, Ingwersen 1996).

Abstract

This research continues to explore the user's evaluation of Web search engines using a methodology proposed by Su (1997) and tested in a pilot study (Su, Chen, & Dong, 1998). It seeks to generate useful insight for system design and improvement, and for engine choice. The researchers were interested in how undergraduate students used four selected engines to retrieve information for their studies or personal interests and how they evaluated the interaction and search results retrieved by the four engines. Measures used were based on five evaluation criteria: relevance, efficiency, utility, user satisfaction, and connectivity. Thirty-six undergraduate juniors and seniors were recruited from the disciplines of sciences, social sciences and humanities. Each searched his/her own topic on all four engines in an assigned order and each made relevance judgements of retrieved items in relation to his/her information need or problem. The study found some significant differences among the four engines but none dominated in every aspect of the multidimensional evaluation. Alta Vista had the highest number of relevant and partially relevant documents, the best relative recall and the highest precision ratio based on PR1, Alter Vista had significantly better scores for these three measures than for Lycos. Infoseek had the highest satisfaction rating for response time. Both Infoseek and Excite had significantly higher satisfaction ratings for response time than Lycos. Excite had the best score for output display. Excite and Alta Vista had significantly better scores for output display than Lycos. Excite had the best rating for time saving while Alta Vista achieved the best score for value of search results as a whole and for overall performance. Alta Vista and Excite had significantly better ratings for these three measures than Lycos. Lycos achieved the best relevance ranking performance. Further work will provide more complete picture for engine comparison and choice by taking into account participant characteristics and identify factors contributing to the user's satisfaction to gain better insight for system design and improvement

Abstract

Examines sex differences in library anxiety, computer anxiety and using computers for library research anxiety in 40 academically oriented high school seniors for 1 year. Finds boys to have higher library anxiety than girls. Girls have a higher anxiety in the remaining 2 categories involving computers. Both sexes improved in all 3 areas except for girls on the computers for library research. Girls may experience less anxiety when using computers in a non mathematical setting but the detrimental effect of computers may compromise girls' attitudes to computer mediated library research

Abstract

Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

Abstract

Since the closing of the Sterling C. Evans Library author/title card catalog on march 6, 1989, librarians have observed a number of patrons who continued to use that catalog, even though NOTIS, the OPAC offered more comprehensive and current access to library holdings. To determine the reasons for this use, the authors prepared a one-page questionnaire, focusing on the users' preference for an inadequate card catalog in an environment which offers a superior OPAC. Card catalog patrons were then surveyed in order to gather data and build a user profile. Survey results were tabulated and analyzed, revealing the underlying reasons for users' preference for the card or online catalog. Conclusions will provide direction for improvements in users' access to online catalogs

Abstract

The Guidelines are a toolbox for libraries to answer for their performance indicators which are described in detail aimed at improving the effectivity of the library: do the opening hours meet the demand of users? To what extent do users find the books they are looking for? In how far do the services of the library fulfil the expectations of the users? The answers to these questions will show to what extent the library fulfils its mission and reaches its goals. Perticularly in times of financial restraint it is necessary for libraries to demonstrate their effectiveness to themselves and the governing bodies

Abstract

HTTP server log files provide Web site operators with substantial detail regarding the visitors to their sites. Interest in interpreting this data has spawned an active market for software packages that summarize and analyze this data, providing histograms, pie graphs, and other charts summarizing usage patterns. While useful, these summaries obscure useful information and restrict users to passive interpretation of static displays. Interactive starfield visualizations can be used to provide users with greater abilities to interpret and explore web log data. By combining two-dimensional displays of thousands of individual access requests, color and size coding for additional attributes, and facilities for zooming and filtering, these visualizations provide capabilities for examining data that exceed those of traditional web log analysis tools. We introduce a series of interactive starfield visualizations, which can be used to explore server data across various dimensions. Possible uses of these visualizations are discussed, and difficulties of data collection, presentation, and interpretation are explored
